Trail: Learning the Java Language Lesson: Object Basics and Simple Data Objects Here's a simple program, called Declaring a Variable to Refer to an ArrayThis line of code from the sample program declares an array variable:Like declarations for variables of other types, an array declaration has two components: the array's type and the array's name. An array's type is writtenint[] anArray; // declare an array of integers Creating an ArrayYou create an array explicitly using Java's Array InitializersYou can use a shortcut syntax for creating and initializing an array. Here�s an example:The length of the array is determined by the number of values provided between { and }.boolean[] answers = { true, false, true, true, false }; Accessing an Array ElementNow that some memory has been allocated for the array, the program assign values to the array elements:This part of the code shows that to refer to an array element, either to assign a value to it or to get its value, you append brackets to the array name. The value between the brackets indicates (with a variable or other expression) the index of the element to access.for (int i = 0; i < anArray.length; i++) { anArray[i] = i; System.out.print(anArray[i] + " "); } Getting the Size of an ArrayTo get the size of an array, you writearrayname.length

Which of the following is the correct way of declaring an array?Which of the following correctly declares an array? Explanation: Option A is correct. Int is the data type used,geeks is the name of the array and [20] is the size of the array.
What is correct syntax of array declaration by initializing elements?We declare an array in Java as we do other variables, by providing a type and name: int[] myArray; To initialize or instantiate an array as we declare it, meaning we assign values as when we create the array, we can use the following shorthand syntax: int[] myArray = {13, 14, 15};
How do you declare and initialize an array in Java?There are two ways you can declare and initialize an array in Java. The first is with the new keyword, where you have to initialize the values one by one. The second is by putting the values in curly braces.
